Box making final IPO updates

UPDATED: The enterprise cloud company will begin trading its shares on the New York Stock Exchange after the opening bell on Friday under the ticker symbol "BOX."

Box is making the final tweaks to its initial public offering paperwork.

In the fourth amendment to its S-1 filing with the U.S. Securities and Exchange Commission, Box reiterated it would be releasing 12.5 million shares of Class A common stock to the public market.

Final pricing is expected to follow later on Thursday.

The enterprise cloud company will begin trading its shares on the New York Stock Exchange after the opening bell on Friday under the ticker symbol "BOX."

The update falls roughly in line with Box's expectations earlier this year, previously projecting it would offer 14.4 million shares between the price of $11 and $13 a share with the aim to raise up to $186.9 million.

"The assumed initial public offering price of $12.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, is substantially higher than the pro forma net tangible book value per share of our outstanding capital stock upon the completion of this offering," according to the most recent document.

Morgan Stanley, Credit Suisse and J.P. Morgan have been enlisted as the lead underwriters.

Box first submitted its S-1 to the SEC last March. Describing itself as "emerging growth company," Box first filed privately thanks to a special rule under the Jumpstart Our Businesses (JOBS) Act, which stipulates a company seeking to go public can file confidentially if it is valued at less than $1 billion.

Yet once revealed, some of the financials prompted some criticism over severe losses matched by high spending rates.

According to the paperwork, revenue climbed 111 percent year-over-year to $124.2 million by the end of January 2014.

But Box also sustained losses of $50.3 million, $112.6 million and $168.6 million year-over-year for the 12-month time frames ending December 31, 2011, January 31, 2013 and 2014, respectively.

Nevertheless, the Los Altos, Calif-based company has been trying to prove its value and battling criticism since launching in 2004, starting with simply justifying the cloud storage element as an easier (and more secure) replacement to the USB thumb drive.

More recently, tech industry analysts and competitors alike have been debating if Box's delayed IPO was a rare demonstration of patience in a vertical that can't seem to slow down - or rather a case of too little, too late.

Opening days on Wall Street are often polarizing in the sense that they're typically viewed as either smashing or disappointing.

However, the following initial months can be volatile as well. Based on the near-microscopic attention Box has experienced since announcing plans to go public last March, 2015 could likely be much more tumultuous.

UPDATE: Box is reportedly setting its IPO at $14 per share, above expectations, according to an underwriter at Morgan Stanley, based on multiple reports on Thursday evening.
